1) kind, sometimes a species (usually of animals)
Groups of living organisms belong in the same created "kind" if they
have descended from the same ancestral gene pool. This does not
preclude new species because this represents a partitioning of the
original gene pool. Information is lost or conserved not gained. A
new species could arise when a population is isolated and inbreeding
occurs. By this definition a new species is not a new "kind" but a
further partitioning of an existing "kind".
